Reaction Conditions

Reaction Steps

Under an argon atmosphere, a mixture of 2-(2-pyridyl)-5-(3-iodophenyl)-1,3,4-oxadiazole (0.03 g, 0.08 mmol), zinc cyanide (0.01 g, 0.12 mmol), and Pd(PPh3)4 (9.1 mg, 0.01 mmol) in N,N-dimethylformamide (2ml) was heated at 80° C. for 2.5 hours. After cooling the reaction mixture was diluted with ethyl acetate and sequentially washed with water (3×50 mL) and brine (50 mL). The organic phase was dried over anhydrous sodium sulfate, filtered, and concentrated in vacuo. Recrystallization of the crude product from 5% ethyl acetate in hexanes, afforded 5.8 mg (30%) of 2-(2-pyridyl)-5-(3-cyanophenyl)-1,3,4-oxadiazole.
